What if someone got a greggs steak bake and ate it outside (or inside) the shop, you STILL wouldn't get the space until they had finished and were ready to go.
Yep this. Excellent point! I wonder if thestrangestthing has an answer for THAT?! 
@Thestrangestthing
Are you OK? Serious question by the way.
You seem to keep switching from being quite angry and upset, to LOL-ing and accusing people of having 'poor comprehension and reading skills' when they give an answer you don't like.
It's been a while since I have seen somebody so utterly obsessed with a thread, not just invested in it, but literally obsessed.
@MsMarvel YANBU.
I would not move out of my parking space, whether it was a free one or a 'paid-for' one, until I was ready. And anyone staring, glaring, or huffing and puffing, can fuck right off.
That said, on most occasions, I would say 'sorry I am not leaving for a while' so the person can move on. But occasionally I like to just sit there and make them wait, just for sheer devilment. Maybe one day thestrangestthing will be the person huffing and puffing and waiting, and I will tootle around, faffing and fussing and eating my crisps, and then fuck off back into the shop, leaving her sitting there red-faced and angry. Just for shits and giggles ya know. 
*disclaimer I rarely carry out such a heinous act,
but I do sit in my car and eat a pack of wotsits and a can of diet coke sometimes if I am hungry and aren't going home for a couple of hours... I rarely hog the car parking space for more than an extra 4 or 5 minutes though!
Is that OK with you strangestthings!?
